[0025] By using the claw sleeve 20 to wrap and protect the outside of the clamping claw, the damage to the back plate when the pneumatic clamping finger 1 is in use can be reduced. The connecting frame 19 can support the two sides of the connecting plate 2, thereby improving the stability of the connecting plate 2 rotating between the two connecting frames 19. Gear 1 8 is meshed with gear 2 17, so the servo motor 18 can be used to drive gear 2 17 to rotate, and the rotation of gear 2 17 drives gear 1 8 to rotate, thereby achieving smooth rotation of the connecting plate 2, changing the inclination angle of the connecting plate 2 when in use, and then achieving synchronous rotation adjustment of the pneumatic clamping finger 1 and the connecting plate 2. The support plate 1 3 can be used to support and reinforce the bottom of the connecting frame 19. The hydraulic cylinder 10 can be used to drive the support plate 1 3 to move, thereby adjusting the distance between the connecting plate 2 and the back plate, which is convenient for the subsequent connection and separation of the pneumatic clamping finger 1 and the back plate. The mold body 5 can be used to support the bottom of the support plate 2 12, so as to facilitate the stable placement of the back plate on the device.

[0026] Embodiment 2

[0027] like Figure 1-Figure 3 As shown, a dual-axis motor 14 is fixedly connected to the bottom of the inner cavity of the mold body 5, one end of the output shaft of the dual-axis motor 14 is fixedly connected to a threaded rod 13, one end of the threaded rod 13 is rotatably connected to a fixed block 11, the bottom of the fixed block 11 is fixedly connected to the base 4, the threaded rod 13 is threadedly connected to a calibration plate 6, one side of the calibration plate 6 is slidably connected to the mold body 5, one side of the calibration plate 6 is fixedly connected to an extension block 9, and one side of the calibration plate 6 is fixedly connected to an infrared ranging sensor 7, the top of the support plate 12 is arc-shaped, and an electric push rod 15 is inserted through the inside of the support plate 12, the bottom of the electric push rod 15 is fixedly connected to the mold body 5, and the top of the electric push rod 15 is fixedly connected to an ejection block 16, and the ejection block 16 is slidably connected to the support plate 12.

[0028] The dual-axis motor 14 can be used to drive the threaded rods 13 on both sides to rotate, and the fixed block 11 can support one side of the threaded rod 13 to improve the stability of the threaded rod 13 when in use. The threaded rod 13 can drive the reciprocating movement of the calibration plate 6, thereby changing the position of the calibration plate 6. The calibration plate 6 is used to assist in calibrating the position of the arc-shaped metal back plate above the support plate 12. The infrared ranging sensor 7 can detect the distance between the back plate and the calibration plate 6, thereby assisting in judging whether there is a positional offset of the back plate. The support plate 12 can be removed from the top of the mold body 5 to facilitate the replacement of the support plate 12. The electric push rod 15 can adjust the height of the ejection block 16, thereby assisting in separating the back plate from the top of the support plate 12, so as to facilitate the rapid removal of the back plate after welding.

[0029] The method of use and working principle of the device are as follows: first, place the arc-shaped metal back plate on the support plate 2 12, and use the servo motor 18 to drive the gear 2 17 to rotate, and the gear 2 17 is meshed with the gear 1 8 to drive the connecting plate 2 to rotate between the two gears 2 17, thereby changing the inclination angle of the connecting plate 2 and the pneumatic clamping finger 1, and then use the hydraulic cylinder 10 to drive the support plate 1 3 to move to the side close to the back plate, so that the back plate is located between the upper and lower claw sleeves 20, and use the infrared ranging sensor 7 to detect the distance from the side wall of the back plate to the calibration plate 6, and judge whether the back plate is placed offset according to the value. When there is a position offset, use the dual-axis motor 14 to drive the threaded rod 13 to rotate, and the calibration plate 6 moves along the threaded rod 13 to the back plate. The extension block 9 is overlapped on the top of the back plate, and the infrared ranging sensor 7 is used to detect the distance from the calibration plate 6 to the side wall of the back plate, until the distance between the two sides of the back plate and the calibration plate 6 is basically the same, and the position calibration of the back plate is completed. After the position calibration is completed, the back plate is clamped and fixed by the claw sleeve 20. At this time, the six surfaces of the back plate are in contact with the mold, and the arc-shaped metal back plate can be stably placed above the mold. The connection of the back plate can be welded by laser equipment. After the welding is completed, the calibration plate 6 moves in the opposite direction, the claw sleeve 20 is separated from the back plate, and the hydraulic cylinder 10 drives the support plate 3 to move to the side away from the back plate, and then the electric push rod 15 pushes the ejection block 16 to move upward, and the back plate is ejected from above the support plate 2 12.
